Abstract
The utility model relates to a combined drawing tool for students, comprising a main body ruler and two slide rulers. Two ends of the main body ruler are provided with a flat head and a curved corner; the middle of the main body ruler is provided with a hollow gap; one end of the hollow gap is provided with an insertion hole; the back surface of the main body ruler is provided with a concave groove; the lower part of the front end of each slide ruler is provided with a probe which is inserted into the insertion hole to slide into the hollow gap; the slide rulers can slide to and fro at one side of the main body ruler under the action of an external force and keeps perpendicular to the main body ruler; a student can draw perpendiculars and parallels as well as rectangles and squares between the main body ruler and the two slide rulers, also can put a circle between the two slide rulers to accurately and rapidly measure the diameter of the circle; and the end head of the hollow gap is positioned at the position of the circular center of the curved corner, therefore, the two slide rulers can slide over the curved corner to be abutted against the flat heads of the two ends of the main body ruler so as to form a lengthened straight ruler with the main body ruler for measuring the length of a longer object. The main body ruler and the two slide rulers can be freely mounted and dismounted, and the combined drawing tool is convenient in use and carrying.
Description
Affiliated technical field
The utility model relates to a kind of student's combination drawing tool.
Background technology
At present, known student's drawing instrument is to mainly contain ruler, set square, graphometer etc., and the pupil begins to learn when drawing parallel lines with vertical line, is difficult to grasp the picture main points, occurs various mistakes easily, brings very big inconvenience to the teacher, becomes a teaching difficulty.Simultaneously, the instrument that lacks a kind of maneuverable measurement diameter of a circle.When the student measures longer line segment, lack a kind of instrument that can the independent assortment lengthening.A kind of student's drawing instrument that the patent No. 2 00820008146.0 is provided has solved a part difficult problem, but the drawing instrument volume that this patented technology provides is bigger, and is not portable, can not freely install, and energy measurement is not than the length of long materials.
Summary of the invention
Begin to learn and draw parallel lines and during vertical line in order to overcome the pupil, be difficult to grasp the picture main points, the problem that occurs various mistakes easily, provide convenience to the teacher, simultaneously, in order to design a kind of maneuverable measurement diameter of a circle, can freely install and measure instrument, now provide a kind of student's combination drawing tool, this combination drawing tool than the length of long materials, easy grasp simple to operate, can make the student draw vertical line fast, parallel lines, rectangle, square etc., and the length of the ruler that can extend, the length of the longer line segment of energy measurement, can also measure diameter of a circle fast, the drafting parallel lines have been overcome, the mistake that occurs easily during vertical line can freely be installed, and is easy to carry.
The new solution technical scheme that its technical problem adopted of this practicality is: design a kind of by the main body chi, two combination drawing tools that the slip chi is formed, there is the scale of measuring length main body chi and slip chi both sides, a middle hollow joint is arranged in the middle of the main body chi, middle hollow joint one end has a patchhole, probe is arranged at two slip chi front end bottoms, probe is made of thin end of probe and probe butt end, thin end of probe and probe butt end all are cylinders, patchhole is a bit larger tham the probe butt end, probe inserts in the hole, slip into middle hollow joint, the width of middle hollow joint and the thin equal diameters of holding of probe, the thickness of middle hollow joint is slightly smaller than the cylindrical height of the thin end of probe, the slip chi has the lower convexity part, the thickness of lower convexity part equates with main body chi thickness, like this, two slip chis can be subjected in a side of main body chi to slidably reciprocate under the effect of external force, and two slip chis keep vertical with the main body chi, keeping parallelism between two slip chis, the student can draw vertical line between main body chi and two slip chis, parallel lines, also can draw rectangle fast, square, the student can also put into circle between two slip chis, measures diameter of a circle fast and accurately.Main body chi two ends are made up of tack and arc turning simultaneously, middle hollow joint end is in the position in the arc center of circle, arc turning, so two slip chis can slip over the arc turning, near the tack at main body chi two ends, with the ruler of a lengthening of main body chi formation, to measure length than long materials.In the main body chi reverse side hollow joint around recessed channel arranged, the thickness of the thickness of recessed channel and probe butt end equates that like this, this drawing instrument is placed on when using on the desktop, the probe desktop that can not rub when the slip chi slidably reciprocates.Main body chi and two slip chis can arbitrarily be installed also and can arbitrarily dismantle, use and very convenient to carry.
The beneficial effects of the utility model are, easy grasp simple to operate, can make the student draw vertical line, parallel lines, rectangle, square etc. fast, and the length of the ruler that can extend, the length of the longer line segment of energy measurement can also be measured diameter of a circle fast, has overcome the mistake that occurs easily when drawing parallel lines, vertical line, and can freely install, easy to carry.

The specific embodiment
In the drawings, design a kind of by main body chi [1], the combination drawing tool that two slip chis [5] are formed, there is the scale of measuring length main body chi [1] and slip chi [5] both sides, a middle hollow joint [2] is arranged in the middle of the main body chi [1], middle hollow joint [2] one ends have a patchhole [3], probe [8] is arranged at two slip chis [5] front end bottom, probe [8] is made of thin end of probe [9] and probe butt end [10], thin end of probe [9] and probe butt end [10] all are cylinders, patchhole [3] is a bit larger tham probe butt end [10], probe [8] inserts in the patchhole [3], slip into middle hollow joint [2], the width of middle hollow joint [2] and the thin equal diameters of holding [9] of probe, the thickness of middle hollow joint [2] is slightly smaller than the thin end of probe [9] cylindrical height, slip chi [5] has lower convexity part [11], the thickness of lower convexity part [11] equates with the thickness of main body chi [1], like this, two slip chis [5] can be subjected in a side of main body chi [1] to slidably reciprocate under the effect of external force, and two slip chis [5] keep vertical with main body chi [1], keeping parallelism between two slip chis [5], the student can draw vertical line between main body chi [1] and two slip chis [5], parallel lines, also can draw rectangle fast, square, the student can also put into circle between two slip chis [5], measures diameter of a circle fast and accurately.Main body chi [1] two ends are made up of tack [7] and arc turning [4] simultaneously, middle hollow joint [2] termination is in the position in the arc center of circle, arc turning [4], so two slip chis [5] can slip over arc turning [4], tack [7] near main body chi [1] two ends, with the ruler of a lengthening of main body chi [1] formation, to measure length than long materials.Main body chi [1] and two slip chis [5] can arbitrarily be installed also and can arbitrarily dismantle, use and very convenient to carry.
In Fig. 2, in main body chi [1] reverse side hollow joint [2] around recessed channel [6] arranged, the thickness of the thickness of recessed channel [6] and probe butt end [10] equates, like this, this drawing instrument is placed on when using on the desktop, slip chi [5] [8] desktop that can not rub of popping one's head in when slidably reciprocating.
